Rome - Matthew Fitzpatrick birdied four of his final six holes on Saturday to hold onto a one-shot lead at the Italian Open heading into the final round.
The 23-year-old MacIntyre, who has broken into the world's top 100 and finished tied-sixth in July's British Open, is projected to leap to seventh in the season-long Race to Dubai standings.
"Just trying to run up that as fast as I can, to end the season really high. Obviously, Race to Dubai, if I get into position coming into the last three (events), you go for gold, don't you."
It was a horrible day, though, for Justin Rose, as the former world number one plummeted down the leaderboard with a seven-over 78 in which he failed to make a single birdie.
